Resumen:
The possible relationship between the superstructures in hydrogen molybdenum bronzes and charge density wave (CDW)-typeinstabilities of their Fermi surface (FS) is analyzed. It is shown that, depending on structural details, two-dimensional, one-dimensional andquite localized bands can be in competition at the bottom of the t2g-block band structure changing the shape of the FS. It is suggested that thetopology of the FS is not the main driving force for the adoption of the superstructures but may be at the origin of some conductivityanomalies of these phases.
